Management and Clinical Outcomes of Eyes With Posterior Segment Intraocular Foreign Bodies Seen at a Tertiary Referral Center

BACKGROUND AND OBJECTIVE: This study aimed to identify the prognostic factors regarding the visual and anatomic outcomes of eyes with posterior segment intraocular foreign body (PS-IOFB). PATIENTS AND METHODS: The medical records of 95 patients who underwent pars plana vitrectomy and PS-IOFB removal between 2004 and 2021 were retrospectively reviewed. Data on anatomical and visual outcomes, as well as preoperative, intraoperative, and postoperative variables were statistically analyzed. RESULTS: The mean age of the patients was 31.9 +/- 12.3 years. The mean follow-up time was 21.9 +/- 28.3 months. The median time interval from trauma to IOFB removal was 9 days. In univariate analysis, there was a positive correlation between initial visual acuity (VA) and final VA (P P < 0.001). A higher ocular trauma score (OTS) was significantly associated with both anatomical and functional success (P P < 0.001). Linear regression analysis showed that OTS was not superior to initial VA in predicting final VA (r r = 0.625 vs r =-0.601). Anatomic and functional outcomes were not affected by the injury site, nature of PS-IOFB, or timing of PS-IOFB removal (P P > 0.05 for all). Subretinal IOFB location, the need for silicone oil tamponade, and endophthalmitis (P P = 0.005, P < 0.001, P = 0.044, respectively) were risk factors for poor visual outcome. CONCLUSIONS: The initial VA, the extent of the initial ocular damage, and the presence of endophthalmitis are important prognostic factors for functional success.
